This is a quilt I designed for one of my classes some years ago. They want all machine done on the sewing machine and large windows. We did this row by row and when it was done, it was complete. I had them put a piece of batting behind each window to give it a puff look. Here is a file of it.

I will check my files to see if I kept the instuctions etc and will send a pdf if you want it.

Since you are folding the fabric in four, I think, it is quite thick and there is really no need for batting but it can be put in, each block. I just put it behind the window. Yes it was all done when you sewed the last row on. That is what everyone loved about this quilt.
